Every vehicle should have jumper cables in the trunk. I learned that lesson the hard way at college. After learning that lesson, I bought these jumper cables and stored them in my trunk. They came in the bag as described, and with a flimsy paper set of instructions if needed. They seemed decent quality from initial inspection. A month after buying these, I had to use them. I can happily say that they performed admirably. They jumped my buddies car no problem and stowed away nicely to be used again. I am very happy with the purchase and hopefully will not need to replace these for years and years to come...cause I'm guessing jumper cables don't spoil, so yea. Great purchase!
